Stephen Colbert to Appear on The Office

Colbert will be a guest star on the popular comedy as Broccoli Rob, a former member of Andy’s a cappella group, Here Comes Trouble. The appearance will come during the Halloween-themed episode, when Andy (Ed Helms) discovers that the competitive Broccoli Rob is spreading a false history of the group, intensifying the rivalry between the two.

The Halloween episode will air on Oct. 25. The final season of the The Office began last night. Be sure to tune in to NBC every Thursday at 9 p.m. for the final season of The Office.
